Hi,

As a reminder about the annoyance of the bug, I get:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build -m ~/tmp/Guix/list-bioconductor.scm -k -v0 --check
guix build: error: all build users are currently in use; consider creating additional users and adding them to the `guixbuild' group
--8<---------------cut here---------------end--------------->8---

where list-bioconductor.scm is below.  It is annoying because the bug
prevents massive rebuild; for instance here the ones from the
Bioconductor archive, useful when massive update or to track
reproducibility issue.


All the best,
simon
